Preparing the Pygmy Borealis XL hull for fiberglassing

The Pygmy Borealis XL kayak is coming along swimmingly! So far I'm very ahead of pace as I only started about five weeks ago and am only working on it a little bit each night.

I won't have the time to fiberglass the inside of the hull until Saturday, but that's OK because there were still a few small steps that needed to be done before then. Besides, you can't fiberglass the hull in an evening. You need to check on it every hour or so until the "green" stage so that you can properly trim the excess fiberglass. If you wait overnight it will probably be too hard to cut easily.

1. ALTERNATIVE STEP FROM THE OFFICIAL PYGMY MANUAL: I added end pours now instead of later as the Pygmy manual suggests. It just makes it easier. See my previous post. The Mylar dams have now been removed and the end pours look great. Plenty of room to drill a 1/2" hole through later for the toggle lines.

2. I also added some thickened epoxy in the ends and down the hull a foot or two until it flattens out. This will add structure as well as make it easier to fiberglass the inside of the hull later.




3. I sanded the inside of the hull and vacuumed it clean.

4. Finally I've added masking tape all along the #4 panels about an inch above the #3/#4 seam. When I fiberglass the inside I will bring the glass up and over the tape. When the fiberglass reaches the "green" stage I will then run a knife along the glass directly under the tape. Then I can simply pull the tape up and the cut fiberglass will come with it. My experience says that this works more than half the time, but it's a bit of a trick. Sounds easier than it is, but hopefully this time will work well. Fingers crossed!



The manual only says to run one strip of tape, but I think it's easier to do if you cover everything above where the glass will go.


Peace!

The Rogue Manual

I've posted about this earlier, but thought it might be good to post it again for anyone who may be interested. I've started to write a manual of tips and tricks for Pygmy solo kayak builders. It covers the taping method, so that your boat doesn't have hundreds of holes all over it. I'm on version 2 now. Version 2 covers several other tips and tricks from myself and from others as collected over time. ATTENTION : Use the manual at your own risk! The only person responsible for any mistakes or problems with the building of your boat is you. Always use the official Pygmy manual that came with your kit. Only do those tips and tricks that make sense to you. If something in the manual doesn't sound right to you, then don't do it! Neither I, nor Pygmy Boats, nor anyone else except YOU is responsible for the safety of your boat and the quality of your build. It's in very rough draft form right now, but if you'd like to read it, please send a $10 donat...

Annapolis Wherry Hull Painted

If you haven't yet, please read my previous post regarding amine blush and primers.  After thoroughly washing the hull with water, and then priming, I was now ready for top coating.  I used Interlux Toplac Plus in Matterhorn White. What a great paint! OMG... this stuff seems to have magical properties! I've never used a paint that does not sag or run, even on vertical hull sides.  Of course, you have to roll on a light coat with a foam roller, but even with a thin coat like that, most paints would still have runs. This one doesn't! And you don't need to tip it either! Just roll it on and walk away.  It gets better too... you don't have to sand after each coat! As long as you roll on a second coat after 16 hours but before 3 days, you don't have to sand. Nice! I did three coats in three days with no sanding between coats. There's a slight bit of orange peel, but most of the surface issues are due to my poor surface prep instead of orange peel. To be honest, ...

Grain Surfboards Waterlog Surfboard Build! Part 1

I'm making a surfboard!  No, I don't actually surf. At least not yet. But we go to Hawaii a lot and a guy has to have a board, right? I didn't kayak either until I built my first Pygmy Coho over 25 years ago. Now I love kayaking. Hopefully the same thing will happen with the surfboard.  The board is a kit from Grain Surfboards . I chose the Waterlog in the 10' version.  I'm super tall and heavy and probably should have selected one of their larger boards, but this is the largest board they have that both Alaska Airlines and Hawaiian Airlines will let my check (They have a 10' 5" limit).  I didn't get any pics of the kit box, but it's just a long (10' plus) cardboard mashup box with sticks in it. The epoxy kit comes separately.  I also bought the "rocker table" that is CNC cut to precisely curve the board as you build it. I highly recommend buying a rocker table if you build one.        The kit comes with white cedar planks that you g...
